Introduction to Entire Net-Work

Entire Net-Work for z/OS, z/VSE, and z/VM provides transparent connectivity between client and server programs running on different physical or virtual machines, with potentially different operating systems and hardware architectures. The currently supported set of server programs includes Adabas, Entire System Server, EntireX Communicator, and any other software program that participates in cross-address communications defined by Software AG. A range of client programs are supported, including those written in Natural, the commonly used 4GL provided by Software AG, web-based applications such as Software AG's Jadabas and Tamino, and currently existing Adabas applications.

At its lowest level, Entire Net-Work accepts messages destined for targets or servers on remote systems and delivers them to the appropriate destination. Replies to these requests are then returned to the originating client application, without any change to the application. Entire Net-Work establishes these connections either through its line drivers.

The method of operation and the location and operating characteristics of the servers are fully transparent to the user and the client applications. The servers and applications can be located on any node within the system where Entire Net-Work is installed and communicating. The user's view of the network targets and servers is the same as if they were located on the user's local node. Note that due to possible teleprocessing delays, timing of some transactions may vary.

How Entire Net-Work Administration Operates

Entire Net-Work provides transparent support for remote and distributed server processing by supporting the existing Adabas database interface. An Entire Net-Work Client call to Adabas invokes the environment-specific Adabas Link Routine (ADALNKX). This routine issues an interregion call to Adabas through the Adabas router (in z/OS, the router is the Adabas SVC). The router, in turn, locates the Adabas nucleus operating in a separate address space or partition, and adds the user call to the Command Queue (CQ). The Adabas nucleus then selects commands from the Command Queue and performs its normal processing.

Entire Net-Work Client establishes its connections using the Simple Connection Line Driver provided with Entire Net-Work Administration.

Entire Net-Work Components

Entire Net-Work is installed on each participating host or workstation system requiring client/server capability. The configuration for a given system includes the following components:

Actual network data traffic is controlled by the Simple Connection Line Driver. Each line driver supports multiple connections to other Entire Net-Work Clients.
